In this chapter, we learn that the sound spirit is the highest level of the nine realms, and that those who can condense it are the most powerful fairies in the realm. In other words, those who are able to condense their sound spirit are the best in the world. We learn that this is the case with the first-ranking pupil of the academy, the Baihu fengyang, and the second-ranking student, the freshman genius, the baihu fujing. The sound spirit stone is the most important thing in the fairy realm, because it determines the level of a person's spirit. If a person can't get to the seventh level, he or she can get out.
